A screw is a type of metal fastener, the name of which comes from the German word Schraube (screw). A screw is a threaded cylindrical metal rod that has a head on one side and a tapered, conical end on the other. The head of the screw creates a bearing surface and performs the role of torque transmission.
The scope of application is used to fasten thin materials, the thickness of which is insufficient to drill a place under the countersunk head.
The material of manufacture is stainless steel. The A4 steel grade allows the use of fasteners with significant temperature changes and in an aggressive and humid environment.
